Simon Cowell wants the world to know once and for all that he is not gay.

The "American Idol" and "X Factor" personality denounced the ever-persistent rumors about his sexuality in a new biography, but also specified that he'd have no shame if they were true, according to the British tabloid The Sun.

Cowell, 52, told TMZ Live that he was "embarrassed" by the release of the book. "It's not my habit to kiss and tell. I've never done it. I've always tried to keep my private life private, and it is unfortunate," he said. "So I was feeling very embarrassed and not gentlemanly at all this week because it's just not my style."

The sharp-tongued talent judge has also been in the news in recent weeks after he reportedly bought his ex-fiancee Mezhgan Hussainy an $8 million mansion as a parting gift. "I'm a hopeless boyfriend," he is quoted by TMZ as saying.

Jeremy Renner

The hunky star of "The Avengers" blasted persistent rumors about his sexuality -- as well as probes into his personal life in general -- earlier this month.
"I want my personal life to be personal, and it's not f***ing true," Renner, 41, is quoted as saying. "And I don't care if you're talking about things that are true, you're still talking about my personal life.. How about I go peek in your window, take what underwear you wore last night, whose husband you were f***ing, and shove that in the megaphone throughout your neighborhood? How does that feel?"
